To Specify the View Scale
You can specify the scale for individual views when you add the view to the drawing, or you can modify the scale at any time. You can set the individual view scales in the following ways:
Using the Drawing Sheet Scale
By default, new views are set to display according to the drawing sheet scale. If you want to display the view at this scale simply place the view.
The drawing sheet scale displays at the bottom of the drawing sheet, or you can view the value in the Scale category on the Drawing View dialog box.
You can modify this value by:
Setting the default_draw_scale configuration file option.
Double-clicking on the drawing sheet scale at the lower-left corner of the screen and then typing the real value or relational expression.
Selecting the drawing sheet scale at the lower-left corner of the screen and then clicking Edit > Value.
Using a Custom Scale
You can define a custom drawing view proportion for individual views.
1. With the Drawing View dialog box open, click the Scale category. The Scale and perspective options display in the dialog box.
2. Click Custom scale. The scale box is enabled.
3. Type a real value or relational expression in the box. Click Apply to see the size of the view with the new scale. If scale is not acceptable, repeat the steps above by entering a different scale value. If the scale is appropriate and no changes needs to be made, select the next appropriate category to define or click Close.

When you apply scale information to a view, the style (such as font, height, and underline formatting) applied to the corresponding view note is reset to the default. However, the color applied to that view note does not change.
Using Perspective
1. With the Drawing View dialog box open, click the Scale category. The Scale and perspective options display in the dialog box.
2. Click Perspective. The distance and diameter boxes are enabled. The unit of measurement displays next to each box.
3. Type the desired value for the Eye point distance, which measures the distance in model space.
4. Type the desired value for the View diameter, which scales the view using paper units.
Click Apply to see the size of the view with the new scale. If scale is not acceptable, repeat the steps above by entering a different scale value. If the scale is appropriate and no changes needs to be made, select the next appropriate category to define or click Close.

When using a relational expression, type only the right-hand side of the expression. The system calculates the left-hand side as the view scale.
